Because this is under an attribution license I must attribute the work in a
manner specified by the photographer without saying they endorse my use
of the image. I would create an online image citation.

I would have to email the photographer and ask for permission to use the image for non-commercial purposes. I would ensure them I wouldn't change the image in anyway.
